Here in sweden we call fish semen "mjölke", which is one letter off from our word for milk. So it's pretty obvious that "milk" literally just means "white cloudy liquid"

You joke but I'm sure if it was invented or brought to Europe now, they wouldn't be permitted to call it butter, most likely. I would vote peanut paste, alliteration is always cool. Also in my country it's more often labeled as 'peanut cream' ('crema', meaning an emulsion with the consistency/texture of cream, not literal milk cream, that would be 'nata').

But it's quite different, companies wanting to label these drinks as milk are doing so with the intent of confuse people into thinking they have similar nutritional qualities to milk, which is deceitful.

Exactly! When a (vegan) person I met discovered horchata ('de chufa', there are other drinks called 'horchata') they commented on using it as their new plant-based milk and I said 'not so fast! This is basically sugar!' but then I read the nutritional info on their oat (I think) 'milk' and was like 'never mind.. this is the same'.

On a side note I didn't know tiger nut is English for 'chufa' which is the (nick) name of my dog. I'm gonna start calling her Tiger nut, it sure suits her!
